What is a Sieve? Make Sure You Choose the Right One

Quick, name the most widely used and cost-effective scientific instrument in your laboratory. Some possibilities come to mind, but our argument is for the ordinary test sieve. In this month’s blog post we discuss the purpose of sieves and how to select the right sieve to fit your particle sizing needs.

Coarse Aggregate Gradation: Test Sieves or Screen Trays?

Does the particle size analysis of coarse aggregates always require a testing screen with large screen trays? In a situation where larger testing equipment is not available, there may still be ways to get the job done. Using conventional round test sieves for large particle sizes is less efficient, but still acceptable if done properly. We discuss test requirements, sieve capacities, and tips to help with equipment selection.

Inventing the Sonic Sifter: How a New Cafeteria Changed the Sieving Industry

Most materials have a lower size limit where sieving with a sieve shaker is no longer sufficient, and the agitation necessary for particle separation starts to break down and destroy some fragile materials. Particles in some substances resist separation and clump together due to electrostatic or moisture issues. For many years, these problems limited the effectiveness of measuring particle size by sieving. This article tells the story of how one man pushed back those boundaries.

Sonic Sieving: The Solution for Particle Size Problems

Test sieves are an efficient, productive, and economical means of characterizing the gradation of dry granular materials. However, the sieving method is not without limitations. If obstacles seem to be making it difficult to produce accurate, repeatable results for finer sizes, Sonic Sieving may be the answer.

Characteristics of Aggregates: Shape, Size & Specific Gravity

Concluding our two-part series on aggregate characteristics. Find out how shape, size, and specific gravity play a part in determining the effectiveness of aggregates in construction projects.

Dust and Noise: Can Better Equipment Help? Part 2: Noise

High decibel levels can potentially be a dangerous element in your materials testing lab. In part two of our special series on workplace safety, you’ll discover some of the best ways to reduce noise levels during testing.

Dust and Noise: Can Better Testing Equipment Help? Part 1 Dust

In part one of our special series on workplace safety, we take a look at how advances in materials testing equipment are minimizing potentially harmful exposure to dust in the lab.

Reference Materials for Test Sieves: Performance Testing for Quality

Reference materials for test sieves are used to evaluate and help ensure continued quality performance of sieves in compliance with ASTM or ISO standards. Sieve Verification Services provide further assurance of compliance through laboratory optical or microscopic examination.

Selecting the Right Test Sieve for Non-Conventional Use
Selecting the Right Test Sieve for Non-Conventional Use

Testing sieves are not a one-size-fits-all product in materials testing. They should be selected based on application, compliance standards, sample composition, level of precision required and more.
